Now we could see much the same thing from Evernote, the popular note-taking app.

Companies like Facebook, Foursquare, and Dropbox are separating their sweeping online services into many smaller, single-purpose applications that specialize in just one thing.

According to venture capitalist Roelof Botha, an investor in Evernote, the company has been grappling with what to do with the single-purpose trend. On one hand, Evernote now has tens of millions of users who enjoy the app as it is. On the other hand, consumers are now searching for very specific services in the app store, and when they do, multi-purpose apps don’t rank as high as single-purpose apps. Search for a PDF scanner, for instance, and even though Evernote’s PDF scanner is a well-known feature among users, other apps that do PDF scanning and only PDF scanning outrank Evernote in search results.

“There are a bunch of people at Evernote who worry about the fact that we’re missing out on an opportunity to serve those customers,” Botha, a partner at Sequoia Capital, said on stage at the TechCrunch Disrupt conference in New York City on Wednesday. “But the only way to address that because of how people search in app stores is to have a standalone app.”

Other companies are facing much the same problem. “With all our portfolio companies that have a significant mobile application, it’s an ongoing debate about whether you should have a single app or whether you need to have multiple that serve different use cases,” Botha said, though he didn’t provide details on who, exactly, is heading in that direction in the near future.

While on stage, Botha also took the time to combat rumors about one of his other portfolio companies, Square, which has faced a spate of rumors lately. The Wall Street Journal, for one, recently reported that Square was in acquisition talks, while others have been buzzing about whether or not Square is postponing an IPO and what that means for the health of the company.

Botha said both of those rumors are absolutely false. “Being on the board of the company, it was a surprise to me to find out we were selling ourselves because none of us are aware of it,” he said, adding that there have been no acquisition conversations whatsoever.

As for those IPO rumors? “Last time I checked, Square never filed, Square never made their filing public, and they never withdrew their public filing,” Botha said. He didn’t deny, however, that Square has discussed the timing around a potential IPO, but Botha says that’s par for the course with late stage companies. According to Botha, the rumors are likely the work of a competitor trying to sully Square’s reputation. “I’ve been trying to think of where the source of this information is,” he said. “I think someone has an axe to grind.”
